SHUTTLE.

'SPECIFICATION forming part of Letters Patent \'|'0. 775.589, dated November 22, 1904,

I Application filed May 18, 1904. Serial No. 208,575. (Model).

i Woodsville, in the county of Grafton and State of New Hampshire, have invented certain new and useful Improvements in Shuttles, of which the following is a specification.

My invention relates to shu ttles used in textile weaving, and is intended to provide a means whereby the bobbin or cop may be threaded to the shuttle by the use of the hands only without the assistance of suction or of any kind of hook.

rl`he shuttles in most common use are provided with a recess or chamber in which is the bobbin or cop and an eye .which pierces the side of one end of the shuttle intothe end of said recess or a continuation thereof. This eye or eduction-tube is too small for the insertion of the fingers, and the usual method of threading is to present a bight or loose endof filling from the cop or bobbin to the inner end of the eye, and then by bringingthe outer end to the lips and drawing in the breath the end is sucked through. The objection to this suction method is that lilaments of fiber are drawn with the breath into the mouth and lungs and that with many colored yarns the dye gets onto the shuttle, the lips, and into the mouth. The liber and dye thus coming in contact with mucous membranes are very unhealthy, and the contact of the lips of different operatives with the same shuttle is very likely to carry contagion and disease.

My invention provides a threader which can be used with great speed and wherein the bight of thread can be picked out easily by the thumb and forefingerof the operator without wetting either.

The invention is shown in the accompanying drawings, in which-d Figure 1 is a top view of the shuttle, showing the first position of the filling. Fig. 2 is a partial cross-section at line w a' and shows the second position of the filling. Fig. 3 is a view similar to Fig. 1, but with a portion of the wood cut away to show the threadguide and the filling as it slides down the guide. Fig. l is a side view showing the last position of the thread. Fig. 5 is a partial cross-section at line y z, showing the way the guide and lilling protrude into a recess from which the filling can be readily picked out by the thumb and forenger. Figs. 6 and 7 show modifications of the gooseneck and eductiontube outlet. Fig. 8 shows the preferred form of eduction-tube outlet and tang.

The cop or bobbin chamber a is extended in the form of a narrow sloth toward the end i of the shuttle from which the filling is to be by a pin e, driven through the wood of the shuttle and said cylinder, as shown in Fig. 2. The inside edge of this thread-guide 7c is substantially straight and runs near the wall of slot but without touching it. rlhe outer edge forms a curve or line `at an oblique angle to the axis of the shuttle (see Fig. 3) from the outside of vthe shuttle, running forward, of such a shape that the portion nearest the outside of eduction-tube dis nearer the inside end of said tube than is the inner end of said edge. The curved portion and the straight portion of the thread-guide must easily clear the upper and lower walls of the chamber c and run together inside slot b into gooseneck f, which rises at an oblique angle to the other portion and to the axis of the shuttle until almost out of the slot b, when it is curved forward in a plane nearly parallel with the axis of the shuttle and forms the pointed head g. The point of this head g nearly touches the wall of slot which is farthest from tube CZ and is provided with a tail or tang L, which slopes backward and outward toward the outlet of tube d. By this construction the thread can be passed by the head on one side only and cannot get baclron the same side, but must form a loop over the gooseneck.

The end of tail /L projects into a recess z',

cut in the wall of slot Z which is nearer the tube Z, whereby as the filling is brought forward by the hand it must always be deflected around the same side of head g, and as it is again brought back it passes by the end of tail Zt and is thereby prevented from slipping off the end of gooseneck f. At the points where gooseneck f joins head g and the body of thread-guide Zr it should form tangential curves, and the curved edge of thread-guide v should form a reverse tangential curve with the side of gooseneck f of such a radius that the filling will not catch at that point.

The curved outer edge of thread-guide Z0 ends in a tang Z, which runs down and across the slot and opening of tube Z into asuitable recess m, cut in the wood.

The better form of outlet for eduction-tube Z is that shown in Fig. 8. In this case an oval hole U is punched at the point where tang Zjoins the body of guide c, whereby when the thread finally reaches tube @Z it bears against the curved side of this hole instead of against the V-shaped bearing. (Shown in Figs. 3 and 4.)

The purpose of tang Zis to allow the filling to be passed into Vtube Z and to prevent its getting out when once in.

An oval recess n is cut in the side of the shuttle about chamber c and guide Zr, whereby the forefinger and thumb may grasp the thread at the point where it finally rests upon guide lo, as shown in Fig. 5.

The operation is as follows: The free end 0 of the filling is brought from cop'or bobbin p forward and around the nose of head g, being directed to the right side by tang ZL, as de scribed. It is then brought back and through recessZ by the end of tail ZL,thus forminga loop over gooseneck f. The tension'is retained, and the loop of thread is thus drawn down and back along gooseneck f until it meets the curved portion of thread-guide Zo. As the distance is less from the outside of this curved portion than from the base of gooseneck f, the loop of threadslips down and out -until it reaches the shortest point on the outside, as shown in Fig. 4. The outside'wall of the shuttle being cut away to form the oval recess n, near the center of whichis the point where the bight of thread lands, and as the thread-guide is fiat and projects clear into this recess n, the loop of thread can be readily picked out with the dry fingers. It can then be passed under the end of the tang Z, through recess m into tube Z, or this can be neglected, and as the shuttle moves back and forth on the lay-beam the thread will be automatically drawn over the end of tang Z and will land in the eductiontube or eye Z, where it is retained by tang Z and remains until the filling of that particular cop or bobbin has run out.

I find thatit facilitates the threading if an oblique slot r is cut in the side of slot Z and the opposite corner of said slot is beveled 0H, as shown at s. I

The purpose of slot fr is that when the thread has been pulled along theguide 76 until it protrudes into recess n it falls into slot r, and when the thread is loosened by the fingers in order to grasp it in the finger-recess n with some yarns there is a slight tendency to spring back out of reach, and this tendency slot r overcomes by holding the thread in place. Another object of slot r is to accentuate the proximity of the outer end of eduction-tube Z to the wall of slot Zi for the purpose eX- plained on page l, lines 75 to 82.

Instead of the head, with the tang just described, I canvuse a straight head, preferably bent away from tube Z, as shown in Fig. 6; but this is objectionable for the reason that if the operator loops the filling about the wrong side thereof; as can be done, the free end comes under the thread-guide Zr: and the fixed end comes over it and cannot be passed through tube Z.

Instead of the form of tang shown at Z, I can use the tang shown in Figs. 6 and 7 at t, which is an extension of a part of the wall of tube Z into a spiral over'which the thread may be easily slipped. This form gives a better bearing-surface for the filling as it is run off the shuttle; but it does not keep the filling in tube Z as well as the other form.

My device is cheaply made, as it consists, substantially, of a sheet ofvmetal stamped out and bent intothe desired shape and readily inserted into the shuttle. the shuttle is cut away very little and is therelfore not weakened, as in some other devices.

The guides and defiectors are so arranged that it is practically impossible for the filling to take any but the desired course around the gooseneck and out to the side opening, and then it stops in its outside position, where it presents a loop which can be instantly picked out and the filling brought into position in the shuttle-eye. It can be operated with great speed and without the operator even looking at the shuttle, as the filling is merely carried forward and then back by the hand and is then immediately picked off the side of the threadguide.

What I claim as my invention, and desire to cover by Letters Patent, is-
